SIGNORS OF ONE-THIRD TO LOUIS PLATTER, OF OAK PARK, ILLINOIS i WINDOW CONSTRUCTION .Application filed January 8, 1931. Serial No. 507,316.

This invention relates to'window constructions, and has' for its particular object to produce avsimple, practical and efficient arrangement for guiding slidably mounted sashes in the window frame so as to frictionally hold the sashes in any raised position without the employment of means other than the sash guiding elements, and to utilize the sash guiding elements so as to obviate the necessity for equipping the window with the usual weather strips or guards. Another object is to provide means for retracting or relieving the sash guiding elements from operable engagement with the sashes, and at the same time providing against accidental dropping of the sashes when released. Further objects and advantages to be attained will hereinafter more fully appear.

The invention consists in the novel general construction and inthe parts,l and combinations and arrangements of parts thereof, as hereinafter described and set forth with particularity in the appended claims.

In the accompanying drawing, Villustrating a practical adaptation of the invention,-V

Fig. 1 is a fragmentary view, in front elevation and partial vertical section, of a window equipped in accordance with the invention, and'parts being brokenaway to foreshorten the figure in length and breadth and yet illustrate a complete window structure; Fig. 2 is'a fragmentary vertical section, on an enlarged scale, illustrating the device ;--f for retracting the sash guiding element and for arresting the downward movement of of the device.

Referring now to the drawing, the numeral 5 designates a' window frame which7 except for the particular details hereinafter described for the purpose of illustrating the present invention,fmay be of any ordinary construction and arrangement. Slidable in the frame is an upper sash 6 and a lower sash 7, said sashes being provided with the usual glass panels or panes 8 and 9, respectively. The sashes are guided on the vertical vside members or stiles 10 of the window frame by spring-pressed bars 1l which are freely slidable laterally in vertical channels 12 provided in the side frame members or Stiles 10, suitable provision being made for preventing endwise movement of said bars 11.

The springs 12, a plurality of which are provided for each of the bars 11, are seated at one end in recesses 14 in the bottoms of the channels 12, and located at regular intervals throughout the length thereof, and constantly under compression, so as to normally press the bars 11 outwardly in the channels 12 and against the adjacent edge portions of the respective sashes 6 and 7. The combined strength of the springs 13 exerts a resilient pressure on the bars 11 sufficient for the purpose of normally holding sashes 6 and 7 in raised position by frictional Contact or braking effect, and, preferably, the sash engaging faces of said bars .11 are provided with rounded longitudinal ribs 15 which are fitted snugly in counterpart grooves 16 provided therefor in the meeting faces of the sashes. By this provision, the necessity for providing the usual parting strip' on theV vertical side frame member or stile 10 is obviated. So, too, inasmuch as the bars 11 extend thev full length of the window frame from top to bottom, they not only serve to guide the sashes and yieldably hold Ythem in differentraised positions, but, further, function eihciently as weather strips or guards.

ByV pressing the bars 11 inwardly in the channels,12, they are disengaged from the sashes and the latter are thereby readily removable from the window frame for convenience in cleaning the windows and for other purposes.

For convenience in retracting the springpressed sash guiding and supporting bars 11, plates 17, having screw threaded central apertures, are embedded in the vertical side members or stiles 10 of the window frame between the channels 12 in which said bars 11 are mounted. Thesev plates 17 are seated Hush with the face of the frame memb er or stile 10, and are secured in place by ordinary wood screws 18, the central screw threaded aperture of the plates registering with recesses 19 provided in the frame member or stile to afford clearance for the inner end of an actuating screw 20, which llatter 1s passed through an aperture 21 in a spanner member or plate 22 of a width sufficient to marginally overlap 4the kparallel pair tof sash guiding and supporting bars 11, as 4bestrshown in Figs. 3 and t of the drawing. The screw is provided with a iXed collar 23 affording an annular shoulder which bears against the outer face of the spanner member or plate 22, said screw being further provided at its outer end with a suitable handle 24 `by which it is conveniently rotated. By turning the screw in one direction in the central aperture of the plate 17, the spanner member `or plate 22 is forcibly moved toward the frame member or stile 10, and presses the guide members or bars 11 inwardly in the channels 12. The plate 22, as shown more clearly in Figs. 2

. and 4, has its upper end portion flanged, as

at 25, so as to afford a ledge or shelf on which the lower edge portions of the .sashes 6 and 7 are supported when the guiding and supporting bars 11 are released from their operable engagement with said sashes.

The supporting shelf 25 serves as a safety stop for limiting the drop .of the sashes when the bars 11 are released, as just above set forth, thereby preventing the sash from becoming damaged and also preventing injury to the `operator while manipulating the screw 20 in the act of releasing said guiding and supporting bars 11. The Spanner members 22, which are provided for retracting the upper end portions of the sash guiding and supporting bars 11, are relatively narrower than the lower plates 22, as the upper plates have no function to perform other than .to straddle the parallel pair of bars 11. The

a form and arrangement of the upper operating screws is identical with that of the screws as shown and described in connection with the lower plates.

Normally, the spanner plates 22 and 22 .1.; are removed from the window frame so as not to interfere with the vertically slidable movement of the sashes on their respective guiding and supporting bars 11. However, when it is desired to remove the sashes from :"1: the window frame, the upper sash is prelimvention as defined by the appended claims.

The invention, therefore, is not limited to the specific construction and arrangementsshown.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

1. In a window construction, a frame having a vertical side member in which a sash is slidably mounted, a spring-pressed guide element on said vertical frame member normally projecting in engagement with the sash whereby to guide the latter and yieldably support it in raised position, and means eX- ternal of the frame for retracting said guide element to release it from operable engagement with .the sash, said means comprising a plate having a shoulder portion for arresting the sash in its `dropping movement after the release of said guide element.

2. In a window construction, aframe having a vertical side member having a slideway in which a sash is slidably mounted, a springpressed guide element -on said vertical frame member normally projected beyond the face of the slideway to engage the sash whereby to guide the latter and yieldably support it in raised position, and means for retracting said guide element and releasing it from operable engagement with the sash, said means comprising a supporting element located on the window frame contiguous to the slideway for the sash, and a detachableelement operably engageable with said supporting element and engagea-ble with said guide element whereby to retract the latter and release it from operable engagement with the sash.

3. In a window construction, a frame having a Vertical side member having Ia slideway in which a sash is slida'bly mounted, a. springpressed guide element on said vertical. frame member normally projected beyond the face of the slidewa-y and engaging the sash where- .by to guide the latter and yieldably support it in raised position, and means for retracting said guide element and releasing it from operable engagement with the sash, said means comprising a supporting element located On the window frame contiguous to the slideway for the sash, and a detachable element operably engageable with said supporting element, said detachable element carrying a member adapted to depress said guide element and arranged to arrest the dropping movement of the sash when the guide element is released from engagement therewith.

4t. In a window construction, a frame having a vertical side member having sash slideways, provided with parallel spring-pressed guide bars extending the length thereof, upper and lower saShes respectively slidably engaged with said guide elements whereby to be guided in their movement and yieldably supported in raised position, and means for retracting said guide elements comprising a socket plate located on the vertical side member of the window frame flush with the faces of the sash slideways between the parallel pair of spring-pressed guide elements, and a detachable actuating member operably engageable With said socket plate, said actuating member carrying a Spanner plate to straddle and engage said parallel spring-pressed guide bars whereby the latter are depressed by the manipulation of said actuating membei'.

In testimony whereof We have signed our names to this specication.
